Package screen: Information

The screen utility allows you to run interactive text-mode programs
(such as login shells) even if it is not possible to control them
interactively all the time (for example, because you are limited by
the way of access to a remote machine.)

For instance, you can do several interactive tasks on the same
physical terminal (a remote shell session) by switching from one virtual
terminal to another with the help of screen utility installed on the
remote machine. Another option would be running a program that needs a
terminal without attaching it to any physical terminal at all
(its start may be scheduled in crontab, or you may want to detach it
when you break the connection to the remote machine).

Install the screen package if you may need to use virtual terminals
managed by the screen utility.
